Application of Pneumatic Tools in Wastewater Filtration

At present, the main production of industrial-grade assembly of pneumatic tools, is committed to the production industry, cutting-edge products, including professional-level specifications of the gun wind approved, wind guns, especially oil-type, hydraulic pulse pneumatic tools is the industry's cutting-edge products. The company's products are mainly used for automobile, motorcycle, electric car, bicycle assembly and maintenance of motor engines, generators, agricultural machinery, air compressors, small machinery and other products for the assembly of the world's automotive, pipe, ship and other industrial manufacturing and automotive After-sales service market widely used, and exported to Europe and the United States and the Middle East and other countries.

   First, the working principle of pneumatic diaphragm

1. The compressed air from the valve into the back of the diaphragm B, so that the right side of the air cavity has been filled with compressed air, the diaphragm will be right to squeeze the right side of the liquid chamber, while the right upper side of the ball valve was open state, The lower right side of the ball valve was closed, the liquid sent out; diaphragm A pull under the diaphragm with the diaphragm B movement is also the right side of the movement, the left air chamber air through the silence of the mouth of the pump body , The left side of the liquid chamber will produce negative pressure, the left side of the liquid chamber above the one-way ball valve was closed, the bottom one-way ball valve was open state, the liquid will enter the left side of the liquid chamber until fully filled the entire cavity. The diaphragms A, B will reach its limits, close to the plane of the body.

2. When the diaphragm A, B reaches the right shift position limit, the air in the right air chamber has been discharged and the ejector pin connected to the diaphragm A is in contact with the selector valve slider and pushed To the right, then, the compressed air will pass through the middle of the valve stem into the main valve on the right (big) side, because the main valve on both sides of the cross-sectional area is not the same, thus forming a pressure, The main valve can only move to the left side of the one-way, compressed air from the main valve center hole and side hole into the right side of the air cavity, so complete the cavity movement. After changing the cavity, the diaphragm B moves to the left. 3. After the cavity, since the compressed air has been inflated to the right side of the air chamber, the diaphragm A, B will move together to the left. Until the limit, and then complete the cavity movement. In this process, the diaphragm A will make the left side of the liquid chamber volume reduction surface to produce positive pressure, the left lower one-way ball valve will move downward to form a sealed space, the left cavity of the liquid can only be discharged from the outlet, The diaphragm B will form a negative pressure on the right side of the liquid chamber (the gas in the chamber is discharged from the muffler), the one-way wrench at the upper right will close and form a sealed space, the liquid in the liquid chamber And so on - an action to discharge. This is a pump action process.

   Second, the advantages of pneumatic diaphragm pump:

Pneumatic diaphragm pumps are easy to operate and require no complex control. In order to prevent the pump from operating in the air chamber with liquid and solid gas valve components caused by failure, usually in the compressed air inlet pipe to install gas-liquid separation and filter clamor. In order to ensure smooth operation of the pump, usually to install the control valve and regulator clamor.

1. Longer service life. Since the passage of the conveying flow medium does not have a sliding part, the unsealed fluid delivered and the clean compressed gas of the control spool are completely separated, so that it is possible to transport the fluid having abrasiveness even containing the solid particles and having a diameter of less than 6 mm.

2. The pump and control valves are two separate pieces for easy inspection and maintenance.

3. No power supply, so there is no spark, so flammable, explosive environment, the use of safer.

4. The pump body can be made of engineering fuel, stainless steel, aluminum alloy or cast iron. Production of the diaphragm can use these materials: fluorine rubber, ethylene propylene rubber, polybutadiene rubber, PTFE, sunny rubber. Choose a different material, the wrench can be used to transport different fluids, so the pump has a relatively wide range of applications, regardless of low viscosity or high viscosity, whether corrosive or viscous, can be transported through the pump.

5. Do not need to pump, can be self-priming work, suction range can reach 6 meters, the export pressure up to 0.6MPa.

6. Flow and head can be adjusted by air intake (pressure range of 0.1-0.8MPa). Changing the intake air volume can change the flow rate of the delivery fluid and change the air pressure to change the height of the delivery.

7. As long as the valve can open or close the gas can switch pump operation, can run without load, and at any time can switch exports, do not worry will be blocked. The pump will not be damaged even if there is no medium pumping or accidental downtime in the event of an accident. Once more than the capacity of the pump, the pump will automatically shut down, with a strong self-protection work. When the pump load returns to normal, the machine can automatically start work.

8. The shearing force on the material is very low, how the work inhalation on how to flow out, so the wrench agitation is very small, especially for the transport of unstable substances.

9. The process of using the pump itself will not overheat to compressed air as the driving force, the exhaust process is an endothermic.

Process, the pump work to reduce the temperature, no harmful gas discharge, safe and environmentally friendly.

10. As the pump volume is too small, light weight, so easy to use mobile.

11. Do not need lubrication, easy maintenance, not because of leakage and pollution of the working environment.

   Third, the application of pneumatic diaphragm pump in wastewater treatment

As the types of waste water on the market, the metal content, solid content, COD and ph different, so a lot of class, the size of the pool there are more than 16 different sizes of corrosion-resistant centrifugal system, Some self-priming liquid pump. Some of the slurry pump with water diversion bucket, a look at the past is more messy. And the actual use of the production of workers to reflect the situation is not very good, some self-priming pump to often irrigation water, irrigation several times not necessarily suck up, very delay the operation time, although the slurry pump water can be filled but can be very good Suck up, but some of the slurry used for a period of time after the seal on the leak on the seal, and the original also appeared in the phenomenon of water diversion bucket.

According to the above, I apply for the selection of two corrosion-resistant pneumatic diaphragm pump trial, and parts of the material contact are selected strong corrosion resistance of fluorine plastic and Yu plastic material, shell ABS material. 1 and 1 sets of self-priming pump in parallel, and the other one with one set of water pump with a pump in parallel, training good operating procedures, and give priority to the use of pneumatic diaphragm pump. The original centrifugal pump used as a backup pump.
